[merged] powerpc-mm-highmem-use-__set_pte_at-for-kmap_local.patch removed from -mm tree

[akpm]

The patch titled
     Subject: powerpc/mm/highmem: use __set_pte_at() for kmap_local()
has been removed from the -mm tree.  Its filename was
     powerpc-mm-highmem-use-__set_pte_at-for-kmap_local.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Thomas Gleixner <tglx@linutronix.de>
Subject: powerpc/mm/highmem: use __set_pte_at() for kmap_local()

The original PowerPC highmem mapping function used __set_pte_at() to
denote that the mapping is per CPU.  This got lost with the conversion to
the generic implementation.

Override the default map function.
